DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a page holding device.

[0002]

2. Description of the Related Art An apparatus which can be attached to a book to hold a desired page in an open state when reading the book, and maintain the state even when the book is moved, is proposed in Japanese Utility Model Publication No. 62-22621.
And Japanese Utility Model Publication No. 5-34952.
In the former, the clip portions provided on both sides of the base sandwich the book on both sides, and in the latter, the U-shaped frame is sandwiched between the grooves between the pages.

[0003]

In the former technique described in the prior art, both sides of the book are clamped by clips taken out from both ends of the lower receiving frame supporting the book. However, there is a problem that irregularities on the lower surface of the book become inconvenient when a force such as writing is applied to some pages.

In the latter case, since the page opening prevention force must be exerted at the most disadvantageous portion even when mechanically considered from the principle of leverage, it is important to secure the clamping pressure and the clamping surface. However, this method has a problem that it is difficult to deal with a book having any page thickness, and further has a problem that the lower surface of the book is irregular as in the former case.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to be able to deal with any page thickness regardless of the thickness of the book. An object of the present invention is to provide a page-opening holder that is free from irregularities and that can be extremely easily mounted.

[0006]

In order to achieve the above-mentioned object, a page-opening holding device according to the present invention has an upper leg piece of a clip attached to one end of a projecting rod extending between pages. , Which is fixed to a posture in which the opening and closing legs can be operated from a direction perpendicular to the rod axis. The fixation of the clip to the end of the support rod body may be a rotatable stop on the opposite side. It is preferable that the projecting rod body is provided with a non-slip shoe on the lower surface of the end opposite to the clip mounting end. Further, in addition to this, the projecting rod body may be bent into an arch halfway.

[0007]

Normally, the projecting rod is stretched between the open pages, and the upper and lower legs of the clip sandwich a predetermined number of pages on the side where the page closing force is strong because the page thickness is thin, and no slippage occurs. To form a fulcrum of the projecting support. On the other hand, the opposite end secures a projecting support point on the page on the side where the page thickness is large and the page closing urging force is weak or hardly occurs.

[0008] Thus, here, a very stable fulcrum is formed as if the treading leg was extended from the side where the vehicle is about to fall. When the clip mounting side is selected, if it is rotatable to the opposite side of the clip rod axis, it can be accommodated even if the mounting side changes to the left or right, and can be stored in a form in which the side projection is eliminated, which is convenient.

If the anti-slip shoe is provided at the support point of the above-mentioned projecting support, the stepping is ensured, and the supporting capability is enhanced. Further, in addition to this, in the case where the middle of the projecting rod body is curved into an arch, the opposing force of the rod shaft against the page closing force increases with resilience, forming an extremely suitable projecting support. .

[0010]

An embodiment will be described with reference to the drawings. FIG.
, One end 1 of the projecting rod 1 spanned between pages
The upper leg piece 2a of the clip 2 is fixed to the position a so that the opening / closing leg can be operated from the direction perpendicular to the rod axis of the projecting rod body 1. It is preferable from the standpoint of feel that the fixing is performed by forming a stepped portion on the end portion 1a and assembling the end portion 1a to make the end portion 1a flush.

In the drawing, reference numeral 3 denotes an anti-slip shoe which is preferably worn on the lower surface of the end 1b opposite to the end 1a. In FIG. 2, the clip 2 is a pivot rod 4 at a pivot point 4.
, And it is preferable to be rotatable to the opposite side of the rod shaft. As shown in FIG. 3, depending on the above-mentioned pivoting attachment, the clip opening operation arm 5 can be pivoted 90 degrees (b), and when the clip opening operation arm 5 can swing, it is further folded inward (c), Can be stored in a bar shape without protruding to the side, which is convenient for carrying. Further, as shown in FIG. 2, since the clip 2 can be freely arranged on both sides of the bar shaft, as shown in FIG. The clip 2 is clamped on the right page side where the power is large (a). When the page turning progresses and the left and right are reversed, the clip 2 must be transferred to the left page side. If the orientation is not possible, there is no choice but to mount it on the upper side of the open page (b), but this is bothersome. However, if the orientation can be changed, it becomes possible to mount the device on the lower side as before (c),
It is suitable.

Depending on the attachment of the anti-slip shoe 3,
The fixing force at both ends for opening the page of this product is firm for both,
Although the open-page holding force is increased, the projecting support rod 1 must endure the closing bias, and in the case of a straight plate, it may bend halfway as shown in FIG. 5A. Therefore, as shown in FIG. 6, it is preferable to reinforce the projecting rod body 1 by bending the middle part of the arch 7 into the arch 7. Then, since the arch 7 resists in proportion to the bending biasing force, a resilient repulsion is generated, and the page opening is reliably maintained (FIG. 5B).

It is preferable that the page contact surface of the lower leg piece of the clip 2 be curved so as not to damage the page.

[0014]

Since the present invention is configured as described above, the following effects can be obtained. (1) The mounting portion (clip holding portion) is one-touch and not the entire page thickness, but only a part of the upper layer. (2) Since it is effective with a total length of only about 110 mm, it is small and is advantageous in storage and transportation. (3) There is no irregularity on the lower surface of the book during page opening, and the book does not tilt due to writing or the like, and is excellent in usability. (4) A complicated mechanism and strong rigidity are not required, and the product is produced at low cost. (5) One end of the projecting support is used to hold a predetermined number of pages by the clip 2 and the other end is a standing upright on the page in a substantially lying posture, and does not damage the paper sheet at all and is easy on a book.
